Shanghai Maple Automobile Co. Ltd, Shanghai 201501, China) Abstract: A further numerical study of the theory that the drag reduction in the turbulence is related to the viscosity profile......
of concentration, shearing rate, pH value and stirring time on its viscosity were studied. The results show that the viscosity of low-concentration Konjac gum increases with the increase of its concentration. The solution presents pseudo-plasticity fluid, which shows the characters of shear thinning as follows: first, its viscosity decreases gradually as the temperature increases, and then increases......
and Technology, Changsha 410004, China) Abstract: Based on constitutive theory of viscoelasticity, the viscoelastic behaviour of concrete pile was investigated. The influence of viscosity coefficient on the stress, displacement and velocity response was discussed. With the increase of viscosity coefficient, the amplitude of stress wave decreases, and the maximum value of the stress wave shifts......
